Apparatus for Cutting a Single Coil and Adjusting Distance thereof

ABSTRACT

An apparatus for cutting a single coil and adjusting distance thereof includes a longitudinal cut module and an adjustment module. The longitudinal cut module is adapted to cut the spiral coil at an end thereof according to an external diameter of the spiral coil, and to synchronously bend the spiral coil to prevent the spiral coil from departing from the document. The adjustment module synchronously adjusts a distance between the auxiliary shaft and the driving shaft, and a position of the longitudinal cut module. Therefore the winding bearing set and the longitudinal cut module synchronously meet spiral coil with the same diameter. By the aforementioned design, an objective of conveniently assembling spiral coil into the holes drilled on the document is achieved.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an apparatus for cutting a single coil and adjusting distance thereof. Specially, the present invention relates to a bending base for bending a spiral coil, and an apparatus for cutting a single coil and adjusting distance thereof.

2. Descriptions of the Related Art

Generally, bulk papers, when collecting and arranging, are collected by paper binder, clipper, glue, blue strip, or spiral coil. But the paper binder, clipper, and glue are easily to be peeled off to miss documents. And the book tightly bound is not convenient for reading. Thus using the spiral coil for collecting the documents with holes drilled on the documents is good at difficult to be peeled, and convenient for reading.

Conventionally, driving the spiral coil into the document is made by hands to drive the spiral coil ring by ring into the holes drilled on the document, and then to cut the extension ends of the spiral coil and to bend the spiral coil for preventing the spiral from departing from the document. However, the aforementioned manual operation is disadvantaged at low speed, low efficiency. After driving the spiral coil, the length needed to be cut varies with the external diameter of the spiral coil. When the length needed to be cut is too short, it cannot prevent the spiral coil from departing from the document, and when the length needed to be cut is too long, the bended portion is not convenient for later use. The manual operations cannot be done by one action and rely on experience of the operator to get better quality of work. Thus, how to drive the spiral coil by more convenient and more efficient solution and to enhance quality of work is a long-term need of users.

The inventor of the present invention is experienced in RD and manufacturing of the related industry. In view of the operations relating to the spiral coil and the document, the inventor was inclined to improve it, and finally succeeded in developing an apparatus for cutting a single coil and adjusting distance to enhance the convenience and efficiency of work.

SUMMARY OF THE INVENTION

Therefore, the primary objective of the invention is to provide an apparatus for cutting a single coil and adjusting distance thereof. Thereby a spiral distance and a position of the longitudinal cut module can be adjusted according to an external diameter of the spiral coil to enhance convenience of utility.

The apparatus for cutting a single coil and adjusting distance thereof that can achieve the aforementioned objective comprises a longitudinal cut module, being set on the base, the longitudinal cut module being controlled by the adjustment module to cut the spiral coil at an end thereof with a length according to an external diameter of the spiral coil, and the longitudinal cut module comprising a bending base for bending the spiral coil, and a longitudinal cut base for cutting the spiral coil.

Thereby, by the performance of the aforementioned technologies, the present invention applies a spacer set between the bending base and the longitudinal cut base to form a gap therebetween for the bending base to be fine tuned, and a rotation pole pivoted to the spacer and the longitudinal cut base, in which the bending base is screwed to the rotation pole and able to be fine tuned when rotating the rotation pole. The present invention is able to enhance supplementary value of products and enhance competition superiority and economic benefit.

The apparatus mainly comprises a longitudinal cut module (40) with a mechanic base (41), and the mechanic base (41) is bottom-up set with a buffer (43), a bending base (44), and a longitudinal cut base (45) along with a lock pole (42). A spacer (420) is set between the bending base (44) and the longitudinal cut base (45) to form a gap (421) therebetween for the bending base (44) to be fine tuned, and a rotation pole (46) is pivoted to the spacer (420) and the longitudinal cut base (45), and the bending base (44) is screwed to the rotation pole (46) (or the longitudinal cut base (45) is screwed to the rotation pole (45)) and able to be fine tuned when rotating the rotation pole (45), as shown in FIG. 9 and FIG. 10.

The bending base (44) has a stationary jaw (441) and a movable jaw (442) for oppositely bending the spiral coil (not shown in Figs.), the longitudinal cut base (45) has a stationary blade (451) and a movable blade (452) for oppositely cutting the spiral coil (65).

Refer to FIGS. 2-4; the mechanic base (41) is set with a driving device (51) on the bottom surface. The driving device (51) has an umbrella gear wheel (510). The mechanic base (41) is set with a cam (52) controlled by the driving device (51) on the top surface. The cam (52) has another umbrella gear wheel (520) in mesh with the umbrella gear wheel (510). The cam (52) is surrounded by a curved leading edge (521), and the top surface of the mechanic base (51) is set with a fine moving switch (53) located on the cam (52) side corresponding to the curved leading edge (521) for controlling turn on/off of the driving device (51). A crank (54) is eccentrically pivoted to the cam (52), a first driving pole (55) and a second driving pole (56) are respectively pivoted to two surfaces of another end of the crank (54) for operating the movable jaw (442) of the bending base (44) and the movable blade (452) of the longitudinal cut base (45).
